ENVIRONMENT: SSI Takes Closer Look At Desalination
Recent Western Cape Business News
SSI Engineers & Environmental Consultants has been awarded a research project to examine the benefits, cost and operational data of desalination and effluent re-use plants in the Southern African context, by the Water Research Commission (WRC) at various locations. The investigation will also look at the operational and financing aspects of these projects.
According to project manager Heinz Strohwald from SSI’s Cape Town office, identified plants include recent desalination and re-use plants established in the southern Cape, Beaufort West, as well as the Goreangab plant in Windhoek, Namibia and possibly the Durban Water Recycling (DWR) project in KwaZulu Natal.
SSI has extensive experience in this field having completed award winning desalination plants for the municipalities of Bitou, Knysna, Sedgefield and Mossel Bay – the country’s largest at 15ML/day - and indirect effluent re-use plant upgrades in George and Mossel Bay where treated effluent is being supplied to the Petro SA refinery in a raw water swop arrangement with the local municipality.
A direct water reuse design for the Hermanus local authority is currently underway.
All these initiatives were designed to supplement existing water supplies stressed due to extended draught conditions in the southern Cape. The main project output will be a research project report published by the WRC which will be of beneficial use to municipal engineers and the water community as a whole, to define real costs for desalination and re-use. This may be used for more effective future planning and comparison of different water supply options.
The project will run over three years and is based on a R1 million grant from the Water Research Commission.
